Description

Technical Field

[0001] The utility model relates to a pneumatic skylight for a numerically controlled lathe, in particular to a pneumatic skylight for a numerically controlled lathe. Background Art

[0002] In order to realize automated production, existing CNC lathes are equipped with some loading and unloading devices for automatic loading and unloading of parts. However, in the prior art, a large part of the loading and unloading devices enter the lathe from the top of the lathe when loading and unloading parts. A skylight is usually provided on the top of the lathe. When parts need to be loaded and unloaded, the skylight is opened, and the skylight is closed after the parts are loaded. In order to realize automation, the skylight is usually equipped with a cylinder, and the cylinder drives the skylight to move to open or close the skylight. However, in actual use, since the cylinder is at a uniform speed throughout the operation, and in order to ensure processing efficiency, the skylight generally moves at a faster speed. Once the skylight moves at a fast speed, the skylight and the machine tool protection will cause impact collision, which is easy to cause deformation of the machine tool protection. At the same time, the machine tool will seriously affect the accuracy of the machine tool when it is subjected to impact and collision for a long time. For this reason, a pneumatic skylight for a CNC lathe is proposed. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and to provide a pneumatic skylight for a CNC lathe.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a pneumatic skylight of a CNC lathe, comprising a skylight tray, a skylight slidably mounted on the skylight tray, and a cylinder arranged on the skylight tray and connected to the skylight for driving the skylight to move; it is characterized in that it also includes an electromagnetic valve 1 connected to the cylinder through a pipeline, an electromagnetic valve 2 connected to the electromagnetic valve 1 through a pipeline, an electromagnetic valve 3, and a silencer connected to the electromagnetic valve 2 and the electromagnetic valve 3, and the silencer connected to the electromagnetic valve 2 is connected to a regulating valve for controlling the exhaust volume of the silencer.

[0005] More preferably, it also includes a magnetic sensing switch arranged on the cylinder for sensing the position of the cylinder rod in the cylinder.

[0006] Further preferably, it also includes a skylight slide rail installed on the skylight tray, and the skylight is slidably installed on the skylight slide rail.

[0007] More preferably, it also includes a travel switch installed on the sunroof tray and a contact member arranged on the sunroof corresponding to the travel switch.

[0008] Further preferably, it also includes a cylinder rack installed on the skylight tray, and the cylinder is installed on the cylinder rack.

[0009] The beneficial effects of the utility model are as follows: a magnetic sensing switch for sensing the position of the cylinder rod in the cylinder is arranged on the cylinder, and at the same time, a muffler one is connected to the solenoid valve two, and a regulating valve for adjusting the exhaust volume of the muffler is connected to the muffler one. After the magnetic sensing switch senses the position of the cylinder rod, the opening and closing of the solenoid valve two and the solenoid valve three are controlled, and then the exhaust volume is controlled through the muffler one, thereby decelerating the movement of the cylinder rod. After the deceleration effect is achieved in the movement of the cylinder rod, the opening and closing of the skylight are reduced in shock and noise, thereby improving the service life. At the same time, the skylight is prevented from colliding with the machine tool protection when opening and closing, thereby preventing the machine tool protection from deformation and affecting the machine tool accuracy.

[0015] Below we further explain the pneumatic skylight of a CNC lathe described in the utility model in conjunction with the accompanying drawings.

[0016] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0017] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense; for example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] See also Figure 1-4 As shown in, a pneumatic skylight of a CNC lathe comprises a skylight tray 1, a skylight 2 slidably mounted on the skylight tray 1, and a cylinder 3 arranged on the skylight tray 1 and connected to the skylight 2 for driving the skylight 2 to move; it is characterized in that it also comprises a solenoid valve 1 4 connected to the cylinder 3 through a pipeline, a solenoid valve 2 5 connected to the solenoid valve 1 4 through a pipeline, a solenoid valve 3 51, and a muffler 1 6 and a muffler 2 61 connected to the solenoid valve 2 5 and the solenoid valve 3 51, and the muffler 1 6 connected to the solenoid valve 2 5 is connected to a regulating valve for controlling the exhaust volume of the muffler;

[0019] A magnetic sensing switch 7 for sensing the position of the cylinder 3 rod in the cylinder 3 is provided on the cylinder 3, and at the same time, a muffler 1 6 is connected to the solenoid valve 2 5, and a regulating valve for adjusting the exhaust volume of the muffler is connected to the muffler 1 6. After the magnetic sensing switch 7 senses the position of the cylinder 3 rod, the opening and closing of the solenoid valve 2 5 and the solenoid valve 3 51 are controlled, and then the exhaust volume is controlled through the muffler 1 6, thereby decelerating the movement of the cylinder 3 rod. After the movement of the cylinder 3 rod is decelerated, the opening and closing of the skylight 2 is reduced in shock and noise, thereby improving the service life. At the same time, it is prevented that the skylight 2 collides with the machine tool protection when opening and closing, thereby preventing the machine tool protection from deformation and affecting the machine tool accuracy.

[0020] In one embodiment, it further includes a magnetic induction switch 7 disposed on the cylinder 3 for sensing the position of the cylinder 3 rod in the cylinder 3; by setting the magnetic induction switch 7, the distance between the tail end of the cylinder 3 rod and the head of the cylinder 3 and the distance between the tail end of the cylinder 3 rod and the tail end of the cylinder 3 rod are set, and these two distances are deceleration distances. When the tail end of the cylinder 3 rod moves to the deceleration distance, the solenoid valve 2 5 and the solenoid valve 3 51 are closed, and the solenoid valve 2 5 controls the exhaust volume by means of the muffler 1 6, thereby reducing the moving speed of the cylinder 3 rod, thereby reducing the moving speed of the sunroof 2;

[0021] The position of the magnetic induction switch 7 can be adjusted according to demand, so that the deceleration distance can be adjusted by changing the position of the magnetic induction switch 7.

[0022] In one embodiment, it also includes a skylight 2 slide rail installed on the skylight tray 1, and the skylight 2 is slidably installed on the skylight 2 slide rail; through the setting of the skylight 2 slide rail, the movement of the skylight 2 is guided.

[0023] In one embodiment, it also includes a travel switch 8 installed on the sunroof tray 1 and a contact member 81 arranged on the sunroof 2 corresponding to the travel switch 8; the travel switch 8 and the contact member 81 are arranged to sense whether the cylinder 3 has moved into place, thereby limiting the movement travel position of the sunroof 2.

[0024] In one embodiment, it also includes a cylinder 3 frame installed on the skylight tray 1, and the cylinder 3 is installed on the cylinder 3 frame; through the setting of the cylinder 3 frame, the cylinder 3 is raised to avoid the cylinder 3 interfering with the movement of the skylight 2.

[0025] When the utility model is in use: through the setting of the magnetic induction switch 7, the moving stroke of the cylinder 3 is divided into a deceleration section, a full-speed section and a deceleration section; when the cylinder 3 is in the process of pushing the cylinder 3 rod to move, the tail end of the cylinder 3 rod is sensed by the magnetic induction switch 7 that the cylinder 3 rod enters the full-speed section at this time, and a signal is sent to the control system of the machine tool, and the control system of the machine tool controls the electromagnetic valve 2 5 and the electromagnetic valve 3 51 to be normally open, and the cylinder 3 rod moves at full speed; when the magnetic induction switch 7 senses that the tail end of the cylinder 3 rod enters the deceleration section, a signal is sent to the control system of the machine tool. System, the control system of the machine tool controls the solenoid valve 2 5 and the solenoid valve 3 51 to be in a normally closed state. At this time, the solenoid valve 2 5 controls the air output with the help of the muffler 1 6 with a regulating valve, thereby adjusting the moving speed of the cylinder 3 rod, thereby adjusting the moving speed of the skylight 2. By reducing the moving speed of the skylight 2 in the deceleration section, the impact and collision caused by the high speed when the skylight 2 contacts the machine tool protection is avoided, thereby achieving the effects of deceleration, shock absorption and noise reduction; by making the moving speed of the skylight 2 at a normal speed in the full speed section, the opening and closing speed of the skylight 2 is ensured, thereby ensuring the processing efficiency.

[0026] The protection scope of the present utility model is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present utility model.
